  • Page 32: X-Ring Application

    2.7 X-Ring Application The industrial switch supports the X-Ring protocol that can help the network system recover from network connection failure within 10ms or less and make the network system more reliable. The X-Ring algorithm is similar to Spanning Tree Protocol (STP) and Rapid STP (RSTP) algorithm but its recovery time is less than STP/RSTP.

  • Page 33: Coupling Ring Application

    2.8 Coupling Ring Application As the illustration shown below, users can use the X-Ring groups to form a coupling ring for redundant backup. It can ensure the transmissions between X-Ring groups not to fail. The following figure is a sample of coupling ring application. Note The Ethernet switches with firmware version before v3.0 use the X-Ring function that has the limitations as follows.

  • Page 34: Dual Homing Application

    2.9 Dual Homing Application The Dual Homing function is to prevent the connection loss between the particular X- Ring group and the upper level/core switch. Assign one port, and only one, to be the Dual Homing port that is the backup port in each single X-Ring group. The Dual Homing function only works when the X-Ring function is active.

    3.3.3 Protocol The user can set the layer 2 protocol setting via this interface. VLAN configuration A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain, which would allow you to isolate network traffic, so only the members of the same VLAN will receive traffic from the ones of the same VLAN.

  • Page 79: Figure 3.3-30 Port Based Mode

    VLAN configuration - Port-based VLAN Packets can go among only members of the same VLAN group. Note all unselected ports are treated as belonging to another single VLAN. If the port-based VLAN enabled, the VLAN-tagging is ignored. In order for an end station to send packets to different VLAN groups, it itself has to be either capable of tagging packets it sends with VLAN tags or attached to a VLAN-aware bridge that is capable of classifying and tagging the packet with different VLAN ID based on not only default PVID but also other information about the packet, such as the protocol.

    RSTP - Port Configuration Here you can configure the path cost and priority of each port. • Select the port in the port column field. • Path Cost: The cost of the path to the other bridge from this transmitting bridge at the specified port. Enter a number 1 through 200,000,000.

  • Page 87: Figure 3.3-38 Snmp System Configuration Interface

    SNMP Configuration Simple Network Management Protocol (SNMP) is the protocol developed to manage nodes (servers, workstations, routers, switches and hubs etc.) on an IP network. SNMP enables network administrators to manage network performance, find and solve network problems, and plan for network growth. Network management systems learn of problems by receiving traps or change notices from network devices implementing SNMP.

  • Page 88: Figure 3.3-39 Trap Configuration Interface

    Trap Configuration A trap manager is a management station that receives the trap messages generated by the switch. If no trap manager is defined, no traps will be issued. Create a trap manager by entering the IP address of the station and a community string.

QoS Policy and Priority Type • Qos Policy: Select the QoS policy rule. Use an 8,4,2,1 weighted fair queuing scheme: The switch will follow 8:4:2:1 rate to process priority queue from High to lowest queue.

  • Page 93: Table 3.21: Igmp Types

    IGMP Configuration The Internet Group Management Protocol (IGMP) is an internal protocol of the Internet Protocol (IP) suite. IP manages multicast traffic by using switches, routers, and hosts that support IGMP. Enabling IGMP allows the ports to detect IGMP queries, report packets, and manage IP multicast traffic through the switch.
  • Page 94 X-Ring X-Ring provides a faster redundant recovery than Spanning Tree topology. The action is similar to STP or RSTP, but the algorithms between them are not the same. In the X-Ring topology, each switch should be enabled with the X-Ring function and two ports of each switch should be configured as the member ports in the ring.

  • Page 95: Figure 3.3-43 X-Ring Interface

    Figure 3.3-43 X-ring interface Note To enable the X-Ring function, users must disable the RSTP first. The X-Ring function and RSTP function cannot both be activated on a single switch. Remember to execute the “Save Configuration” action, otherwise the new configuration will lose when switch powers off.

    3.3.4 Security In this section, you can configure 802.1x and MAC address table. 802.1X/Radius Configuration 802.1x is an IEEE authentication specification which prevents the client from connecting to a wireless access point or wired switch until it provides authority, like the user name and password that are verified by an authentication server (such as RADIUS server).

    802.1x/Radius - Port Configuration You can configure the 802.1x authentication state for each port. The state provides Disable, Accept, Reject, and Authorize. • Reject: The specified port is required to be held in the unauthorized state. • Accept: The specified port is required to be held in the Authorized state. •...

    802.1X/Radius - Misc Configuration • Quiet Period: Set the period which the port doesn’t try to acquire a supplicant. • TX Period: Set the period the port waits for retransmit next EAPOL PDU during an authentication session. • Supplicant Timeout: Set the period of time the switch waits for a supplicant response to an EAP request.

  • Page 100: Figure 3.3-48 Static Mac Addresses Interface

    MAC Address Table Use the MAC address table to ensure the port security. You can add a static MAC address; it remains in the switch's address table, regardless of whether the device is physically connected to the switch. This saves the switch from having to re-learn a device's MAC address when the disconnected or powered-off device is active on the network again.
